I've seen a couple on Etsy that might work for you, though I'm not sure what size you're looking for. The sellers are:
twinkletoesdiapers
littlemoosediapers

I haven't used anything from these sellers (yet... DS ready to pop out any day now), so I can't vouch for their quality, but they seem to have gotten good reviews. Littlemoose even gave me a few tips for making my own upcycled covers!

Not that I am but if I happen to be the WAHM with the long wait just PM me and I can work with you : ) I am just pregnant so some days are slow going so I need a turnaround time that can work with that so my customers don't wait longer than I quote them
If I am not the WAHM of course you can just disregard this message
